CNN News:特朗普称美国疫情已过峰值 计划重启美国

Some American intelligence officials say it may never be known exactly where COVID-19 came from. Scientists originally believed it started spreading from a seafood and animal market in Wuhan, China. But we told you last week how researchers didn't all agree with that explanation. And now U.S. government investigators say they're looking at several theories for how the virus got into people and started spreading including the possibility that it came from a Chinese research laboratory in Wuhan.

American intelligence officials are examining whether some kind of accident led to COVID-19 getting out of the lab and into the public. They say they don't think it was developed as a biological weapon. They also say it's too early to draw any conclusions. And the Chinese government has denied that lab research led to the coronavirus pandemic. But the search for answers continues as the disease continues to spread. U.S. President Donald Trump says America is past the peak on new coronavirus cases so he's looking at ways to reopen certain parts of the country. But some health experts say more testing is still needed before that should happen.
And the governor of New York, the state with the most cases, says businesses and schools there will stay shutdown until at least May 15th
